There's no quantised point releases. A fully updated 8-stream install is the equivalent of the last point release of RHEL8 plus some other bits and those other bits will accumulate over the 6 months and eventually form the next point release. You will continue to get updates in 8-stream until the last RHEL8 point release (8.10) in 2024. It is unclear to me what will happen then - will 8-stream remain dormant and get security fixes only? Will it be removed completely (either deleted or put in vault)? Will there be an "upgrade" mechanism to get to 9-stream? P.
